FOLDING SEAT FOR WINDOW-CLEANING.

To all whom it may concern:

Be it known that I, CHARLES IV. Boos'r, a citizen of the United States, and a resident of Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Folding Seats for Window-Cleaning, of which the following is a specification, reference being had to the accompanying drawings as constituting a part thereof.

This invention has for its object to provide a scaffold-like or j ack-like device which may be readily aflixed to thesill of a window in such manner as to project exterior of the building and serve as a seat or support for a windowcleaner, while engaged in cleaning the outer faces of a window-pane in a building; and my invention also has for its purpose to so construct the parts of my device that the same, when not in use, may be folded together in a compact parcel, convenient to be stowed away, also thereby rendering the same convenient for carrying about.

My invention is constructed and used in practice as illustrated in the accompanying drawings.

In the latter, Figure 1 shows in section a part of a window casing with my device arranged as in practice, the wooden seat-board and the back rail of my device being shown in broken outline so as not to obscure the supporting frame-work; Fig. 2 is a back-end view of my device, illustrating the'folding thereof; and Fig. 3 is a detail of construction, being a modification of the general plan of construction of the frame sides of my device, as shown in Fig. 1, and having for its purpose to render the frame adjustable to window sills of varying width.

Referring now to the reference letters in the several views: The frame work of my window seat or jack comprises flat metal bars a, (1/, turned edge wise, except at their inner ends 6, where the bars are given a quarter twist and formed with hooks 0, so as to be adapted to be clamped over thesill d of the window casing 62. The bars a, a are curved at their outer ends 6, and from thence continued downward at an angle so as to provide struts f, the latter being rigidly connected with the members a, a by braces g, riveted to the parts to brace the same. The bars a, a are further made with registering slots h, t, to receive the bent or loop-ends of transverse braces or members j, 70. In the transverse braces j, k, are inserted, through per- Specification of Letters Patent.

Serial No. 408,704..

forations therefor provided, screws Z, Z, m, m, to secure in place the seat-board or sill n, (shown in broken outline in Fig. 1).

The device may be used, as now described,

without any back rail or rest. It is, however, preferable and safer to provide a back-rest. This is accomplished by affixing to the curved ends 6 of the bar-members a, a, by screwbolts 8, or other convenient means, vertical bars 0, p, the upper ends 0, p of which are given a quarter twist so as to come flat against the back rail q, also conveniently affixed in place by screw-bolts r.

The modification, Fig. 3, represents the bar-members a a made in two sections t, a, respectively provided with registering slots 1), o, and the parts being movably secured in the position to which adjusted by screwbolts w. When my frame is so made, the struts g would have to be afixed to the piece t of the side-bars. In all other respects, the modified arms would be just the same as the arms a, a, the only object being, in the modification, to provide for the lengthening of the portion carrying the hook part 0, so as to adapt my device to be applied to a window casing, whether made with a wide or a narrow sill.

I claim: 1

1. A window seat or jack, comprising a frame consisting of two horizontal side bars made with hooks at their inner ends and curved portions at their outer ends having extensions downward at an angle constituting struts, transverse braces and connections between the same and said side bars adapted to allow the struts and side bars to be folded inward against the seat-board in a direction transverse to the longitudinal axes of the side lgars, and a seat-board secured to the side ars.

2. A window seat or jack, comprising a frame consisting of two horizontal side bars made with hooks at their inner ends and curved portions at their outer ends having extensions downward at an angle constituting struts, transverse braces and connections between the same and said side bars adapted to allow the struts and side bars to be folded inward against the seat-board in a direction transverse to the longitudinal axes of the side bars, vertical braces connecting the side bars and the struts respectively, and a seat-board secured to the side bars.

3. A window seat or jack, comprising a frame consisting of two horizontal side bars made with hooks at their inner ends and curved portions at their outer ends having extensions downward at an angle constitut' ing struts, transverse braces and connections between the same and said side bars adapted to allow the struts and side bars to be folded inward against the seat-board in a direction transverse to the longitudinal axes of the side bars, and a seat-board secured to the side bars, vertical bars aflixed to the outer ends of and projecting above the side bars, and a back rail al'fixed transversely to said vertical bars.

4. A window seat or jack, comprising a frame consisting of two horizontal side bars made with hooks at their inner ends and curved portions at their outer ends having extensions downward at an angle constitut mg struts, transverse braces and connections between the same and said side bars adapted to allow the struts and side bars to be folded inward against the seat-board in a direction transverse to the longitudinal axes of the side bars, vertical braces connecting the side bars and the struts respectively, and a seat-board secured to the side bars, vertical bars affixed to the outer ends of and projecting above the side bars, and a back rail affixed transversely to said vertical bars.
